An organism's "trophic level" refers to an organism's "trophic level" refers to its position in the food chain where it lives the intensity of its competition with other species whether it is early or late in ecological succession the rate at which it uses energy

  Its position in the food chain

Explanation:  The trophic level of an organism is a position of an organism in a food chain. It is a step in the ecosystem, that is, in the nutrient series, it should be said that there are several steps, so based on which step this organism is located in ecosystem, is determined the position of that organism in the ecosystem, i.e in the food chain. So you can say that it is the position of an organism in the food chain based on what step is involved. The first trophic level is the level with primary producers and these are plants, then herbivores, and carnivores, while levels four and five are predators, that is, top predators. The point is that the most capable "organisms" are predators at the top of the chain.

In addition to these, there are so-called separate trophic levels and there are so-called decomposers, i.e bacteria and other micro-organisms that decompose dead animals and waste, and from this they create fertile soil for the plant growth as a first step in the chain, but other producers can use it, too.
